Hypoestes plant named ‘G15180’

ABSTRACT

A new and distinct cultivar of  Hypoestes  plant named ‘G15180’, characterized by its upright and mounding plant habit; vigorous growth habit; freely branching habit; large dark green and white-colored leaves; and relative tolerance to high light conditions.

Botanical designation: Hypoestes phyllostachya.

Cultivar denomination: ‘G15180’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hypoestes plant, botanically known as Hypoestes phyllostachya and hereinafter referred to by the name ‘G15180’.

The new Hypoestes plant is a product of a planned breeding program conducted by the Inventor in Bellefonte, Pa. The objective of the breeding program is to create new vigorous Hypoestes plants with attractive leaves and high light tolerance.

The new Hypoestes plant originated from an open-pollination during the spring of 2015 in Bellefonte, Pa. of an unnamed proprietary seedling selection of Hypoestes phyllostachya, not patented, as the female, or seed, parent with an unknown proprietary seedling of Hypoestes phyllostachya as the male, or pollen, parent. The new Hypoestes plant was discovered and first selected by the Inventor as a single plant within the progeny of the stated open-pollination in a controlled greenhouse environment in Bellefonte, Pa. on Sep. 11, 2015.

Asexual reproduction of the new Hypoestes plant by terminal cuttings in a controlled greenhouse environment in Bellefonte, Pa. since Sep, 11, 2015 has shown that the unique features of this new Hypoestes plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Hypoestes have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘G15180’. These characteristics in combination distinguish ‘G15180’ as a new and distinct Hypoestes plant:

-   -   1. Upright and mounding plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Large dark green and white bi-colored leaves.     -   5. Relatively tolerant to high light conditions.

Compared to plants of the female parent selection, plants of the new Hypoestes differ primarily in the following characteristics:

-   -   1. Plants of the new Hypoestes are more vigorous than and not as         compact as plants of the female parent selection.     -   2. Leaves of plants of the new Hypoestes are smoother than and         not as crinkled as leaves of plants of the female parent         selection.     -   3. Plants of the new Hypoestes are more tolerant to high light         conditions than plants of the mutation parent selection.

Plants of the new Hypoestes can also be compared to plants of Hypoestes phyllostachya ‘Splash Select White’, not patented. In side-by-side comparisons, plants of the new Hypoestes differ primarily from plants of ‘Splash Select White’ in the following characteristics:

-   -   1. Plants of the new Hypoestes are more vigorous than and not as         compact as plants of ‘Splash Select White’.     -   2. Plants of the new Hypoestes have thicker leaves than plants         of ‘Splash Select White’.     -   3. Plants of the new Hypoestes are more tolerant to high light         conditions than plants of ‘Splash Select White’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Hypoestes plant.

The photograph at the bottom of the sheet is a side perspective view of a typical plant of ‘G15180’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical plant of ‘G15180’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late summer and early autumn in 11.5 cm containers in an acrylic-covered greenhouse in Carleton, Mich. and under cultural practices typical of commercial potted Hypoestes production. During the production of the plants, day temperatures ranged from 18° C. to 28° C. and night temperatures ranged from 18° C. to 25° C. Plants were ten weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
